Av organic teeb meem (SOM) yog organic teeb meem feem ntawm av , muaj cov nroj tsuag thiab tsiaj detritus ntawm ntau theem ntawm decomposition, hlwb thiab cov ntaub so ntswg ntawm av microbes, thiab tshuaj uas av microbes synthesis.
Ib yam li ntawd, nws yog nug, dab tsi yog txhais los ntawm cov khoom organic?
Organic teeb meem (los yog cov khoom siv organic ) yog teeb meem uas tau los ntawm cov kab mob uas muaj sia nyob tsis ntev los no. Nws muaj peev xwm ua kom lwj, lossis yog cov khoom tawg; los yog muaj li ntawm organic tebchaw . Tsis muaj ib tug txhais ntawm organic teeb meem nkaus xwb. Cov organic teeb meem hauv av los ntawm cov nroj tsuag thiab tsiaj txhu.
Tom qab ntawd, lo lus nug yog, dab tsi yog piv txwv ntawm cov organic teeb meem hauv av? Qhov chaw nyob ntawm av organic teeb meem suav nrog ntau yam kab mob, xws li kab mob, kab mob, fungi, protozoa, thiab algae. Nws tseem suav nrog cov cag ntoo thiab kab, kab hauv av, thiab cov tsiaj loj, xws li moles, woodchucks, thiab luav uas siv. qee ntawm lawv lub sijhawm av.
Ntawm no, dab tsi yog av organic teeb meem thiab nws qhov tseem ceeb?
Organic teeb meem suav nrog cov nroj tsuag lossis tsiaj cov khoom uas rov qab los av thiab dhau mus tus txheej txheem decomposition. Hauv ntxiv rau muab cov as-ham thiab chaw nyob rau cov kab mob nyob hauv av , organic teeb meem kuj khi av particles rau hauv aggregates thiab txhim kho tus dej tuav peev xwm ntawm av.
Peb piv txwv ntawm cov organic teeb meem hauv av yog dab tsi?
Cov kab mob, fungi, nematodes, protozoa, arthropods, thiab lwm yam. Av Organic Matter - Hais txog organic feem ntawm av , suav nrog peb thawj qhov chaw suav nrog me me (tshiab) cog cov seem thiab cov nyob me me av cov kab mob, decomposing (active) organic teeb meem , thiab ruaj khov organic teeb meem (humus).
